Again, what end users are you taling about here? An application that wants to prcess key (or button) presses?

Having support 2 different interfaces for regular applications is also a waste of time and effort. The applications who don;t care about IRC protocol decoding should be able to just work with standard input interface. -- Dmitry -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
